Antitumor Effect of a Combination of Lysine, Proline, Arginine, Ascorbic Acid, and Green Tea Extract on Pancreatic Cancer Cell Line MIA PaCa-2.
Topics: MedicineResearchers report that the formulation of green tea extract, lysine, proline, and ascorbic acid, have tested as a promising adjunct to standard treatment of pancreatic cancer.
Current treatment of pancreatic cancer is generally associated with a poor prognosis, even if diagnosed early, owing to its aggressive rate of metastasis and non-responsiveness to chemotherapy and radiotherapy once metastasis occurs.
The matrix metalloproteinase(MMP) family of enzymes contribute to both normal and pathological tissue remodeling. MMPs play a key role in the migration of normal and malignant cells through the body and also act as regulatory molecules, both by functioning in enzyme cascades and by processing matrix proteins, cytokines, growth factors and adhesion molecules to generate fragments with enhanced or reduced biological effects. MMPs have received much attention in recent years for their role in various malignancies, and have been implicated in tumor invasion, metastasis, and angiogenesis. Investigators, prompted by the reported antitumor properties of ascorbic acid, lysine, proline, and green tea extract, researched the effect of a combination of lysine, proline, arginine, ascorbic acid, and green tea extract on pancreatic cancer cell line MIA PaCa-2 for viability(here, here), MMP expression, invasion, and morphology.
Viability was evaluated based on cell proliferation by MTT assay and MMP expression in condition media by gelatinase zymography. Invasion through Matrigel was assayed and morphology was observed by hematoxylin and eosin staining. Data was analyzed by an independent sample "t" test.
